浮力

毕达哥拉斯作为勾股定理（a² + b² = c² ）的作者，对于当今许多学生都是很熟悉。除此之外，还有更丰富的毕达哥拉斯哲学思想。他是一个深邃的思想家，涉及宗教，灵魂的本质，和宇宙的和谐等方面。 他利用毕达哥拉斯杯向学生们解释了凡事都要适度的精神：当装满半杯时，杯中的液体一滴也不流出来，但是完全装满水后，所有的液体就会通过底部的孔完全流出。我们的毕达哥拉斯杯由洁净的吹制玻璃制成的。构造的秘密在于一个处于杯中心的虹吸管。我们可以利用历史的背景向学 ... 更多

Set comprising five rectangular prisms made of various materials and a transparent block with a hollow body, all with the same dimensions for demonstrating Archimedes’ principle. The bodies have 2-mm bores by which they can be suspended ... 更多

Apparatus for demonstrating buoyancy of fluids, consisting of a flat-ground glass tube and a plastic disc with rubber covering to form a base plate to which a long string is attached. The base plate makes a watertight connection with the ... 更多

阿基米德原理装置用于演示阿基米德在液体中浮力的原理。它也可以用来测定未知流体的密度。它由一个带把手和钩子的桶和一个精确装配的带环的固体圆筒组成。 更多

它用来演示物体在水中的漂浮，下沉和上升。一个由彩色玻璃制成的空心物体，带有一个狭窄的开口。这个物体可以在装满水的圆柱体中漂浮，通过对橡皮冒施加压力来实现漂浮，下沉和上升。这个橡皮冒适合的圆柱体直径大约从30毫米到40毫米如U14206不需支撑物的圆柱体。 运送范围: 1个浮沉子 1个橡皮冒 附加的器件： U14206不需支撑物的圆柱体，无刻度 更多
